uniform magnetic field. The electric field points up and the magnetic field points out of the page in the diagram below. Which path will the positive particle follow? (All paths shown are in plane of the page.). Answer: The (+) particle will feel a force F E = qE due to the E-field along the direction of the E-field. As it starts moving Representing Magnetic Fields. The representation of magnetic fields by magnetic field lines is very useful in visualizing the strength and direction of the magnetic field. As shown in (Figure), each of these lines forms a closed loop, even if not shown by the constraints of the space available for the figure.

The magnetic field strength is a measurement of the magnetic field's strength and direction at a particular point near the magnet. It is expressed in Gauss or Tesla (1 Tesla = 10,000 Gauss). It depends on the size, shape and grade of the magnet, where the measurement is performed, and the presence of any other magnets or ferromagnetic materials nearby.

(a) at which point in the diagram is the magnetic field strength the smallest?. A particle with charge of 3.0 • 10-5 C moving with a velocity of 410 m/s enters a 3.0 T magnetic field at an angle of 40° to the magnetic field. What is the magnitude of the magnetic force that acts on the charge as it enters the magnetic field? At which point in the diagram is the magnetic field strength (a) the smallest and (b) the largest? Explain. Step-by-step solution. For a small-volume liquid metal motor, as shown in Figure 8A-D, the magnetic field strength was the smallest near the magnetic field boundary and the magnetic force on the droplet motor was weak. Therefore, the motor oscillated in a small range nearby. The less concentrated the field lines, the smaller the force. If the gravitational field strength at any point is known, then the size of the force can be calculated. Gravitational field strength is a vector quantity: its direction is towards the object that causes the field. Always use the given value for g.

Estimate the magnitude of the electric field midway between them and state any assumptions that you make. d. On the diagram, draw an equipotential line that passes through point D and intersects at least three electric field lines.

The magnetic field along their axis of symmetry at a point P a distance x from their center can be determined for each coil and the fields can be added together for the final result. If the currents in each coil are in the same direction, then the fields will complement each other to produce a strengthened magnetic field at each point. Note that the arrow representing the external field points North. 3. The difference in energy between the two spin states is dependent on the external magnetic field strength, and is always very small. The following diagram illustrates that the two spin states have the same energy when the external field is zero, but diverge as the field increases. Since electric field is a vector quantity, it can be represented by a vector arrow. For any given location, the arrows point in the direction of the electric field and their length is proportional to the strength of the electric field at that location. Such vector arrows are shown in the diagram below. At which point in the diagram is the magnetic field strength (a) the smallest and (b) the largest? Explain. Problem 1. Step-by-step solution. Step 1 of 5.

Transcribed image text: Rank the magnitude of the magnetic field at points A, B, and C. Explain your ranking. If you cannot rank the magnetic field at some of the points, explain why you cannot. The diagram below shows magnetic field lines near some magnets. Only a small region is shown.

Solution: The cylindrical soft iron core placed inside the galvanometer increases the magnetic field strength, thereby improving the sensitivity of the instrument. It also makes the magnetic field radial so that the angle between the plane of the coil and the magnetic lines of force remains zero at all times during the rotation of the coil.

Since the current is flowing in the -x direction, the magnetic field points in the direction of the cross product 1 ()−׈ˆirˆ =()−i×(cosθ sˆj+inθθ kˆˆ)=sin cˆj−osθ k (4.2) Thus, we have 0 1 22 sin cosˆ ˆ 2 I az µ θθ π = + B j−k G (4.3) For the right wire, the magnetic field strength is the same as the left one: B12=B.

At point 1 the induced magnetic field will point into the page to oppose the increasing external field. This means the current must be CLOCKWISE (use RHR2) At point 2 the induced magnetic field will point into the page, in the same direction as the decreasing external field. To oppose a decrease you add to the field in the same direction.

Homework Equations Not sure only equation it gives in book ins I=Io*cos^2(theta)

If we consider the space around points B, C, and D, we see that it’s point D which has the fewest field lines nearby. The lowest magnetic field line density indicates the smallest magnetic field strength. Therefore, of the four points, the magnetic field is weakest at point D.

presence of that field. Magnetic field: 1) A moving charge or current creates a magnetic field in the surrounding space (in addition to E). 2) The magnetic field exerts a force F m on any other moving charge or current present in that field. - The magnetic field is a vector field vector quantity associated with each point in space.

The strength of the field at any point is determined by the distance from the wire axis. Field strength is inversely proportional to distance, so the field at a point twice as far from the wire will be half as strong. ... From greatest to smallest net magnetic field strength, ...
